Spinning the top quark
We propose to measure the threshold lepton asymmetry, that is the forward-backward asymmetry of the charged lepton in ttbar events near the production threshold. At threshold top quark pairs are produced at rest and have vanishing orbital angular momentum, therefore the sum of the top spins equals t...
